“Well, we're in our new house. Let's get a new pet to get along with it,” Mrs. Brown said to her husband.” That sounds like a pretty good idea,” he answered. “Do you want to see the ads in the newspaper？” “No. Let's go to the animal shelter. Many pets there need homes. Since tomorrow is Saturday, we can both go,” she said.
The next morning the Browns met Mr Snow at the animal shelter. “We want to be sure that the pets here go to good homes,” Mr Snow said, “So I need to ask you some questions.”
After they talked for a while, the Browns decided to get a small dog. It wouldn't need a big house or a big yard. A small dog would bark（吠）and warn them if someone tried to break into their house. After Mr Snow gave the Browns a book on pet care, they chose one and wanted to take her home right away. But the animal doctor hadn't checked her yet. So Mr Snow told them to return on Sunday.
On Sunday afternoon the Browns went to the animal shelter. The animal doctor said, “Shadow has had all of her shots(预防针). She will be healthy.” The browns thanked the doctor and took Shadow home.

Once a baby cries, the parents will go to see what happened as soon as possible. According to a new study, a baby’s cry can make adults react very quickly, even if they are not related(相关的).
Oxford University researchers used a game called Whack-a-mole for the study. The game needs people to hit one buttons(按钮). The players must react as quickly as they can to hit the button that lights up at random(随机的). It is a game that requires speed and accuracy(准确度).
The study included 40 men and women volunteers aged 19 to 59. Some of them had sons or daughters but none had a baby at the time. They played whack-a-mole after listening to different sounds, including babies’ crying, the crying of adults in trouble and birds’ song that sounds like babies’ crying.
The volunteer’ scores  were higher after listening to the sound of crying babies. Men and women had similar scores. The results showed that a crying baby gets special attention.
“Few sounds make people react quite like the cry of a baby,” said Morten Kringelbach of Oxford’s psychiatry department, who led the study.
He added that a baby’s cry can increase adults’ heart rate and blood pressure. This is understandable, because in the course of human evolution(进化), taking care of babies has always been an important job for adults. When a baby is hungry or feeling bored or unwell, it will cry. As a result, human brains and bodies develop a special reaction to a baby’s cry.
【小题1】According to the passage, how many volunteers took part in the study?
